1. 0:01not
2. 0:03>> how to fail.
3. 0:06>> So, this will be
4. 0:09um
5. 0:11a way to pass the SWP.
6. 0:15Not my way. It's the way according to
7. 0:17the um assessment guide and the teachers
8. 0:21notes.
9. 0:24So, first off, going to walk into the
10. 0:26room. He's going to give you the
11. 0:28scenario of the appliance you're working
12. 0:31on
13. 0:33in association with the switchboard, its
14. 0:35location. So the switchboard will be
15. 0:38located another part of the residence in
16. 0:41front of the house. The appliance will
17. 0:44be at the back of the house. All right?
18. 0:47You may have a couple of kids running
19. 0:49around.
20. 0:51>> So you have to be safe. All right. First
21. 0:54thing to do
22. 0:56JSA.
23. 0:59>> So, is the workplace safe? Will it
24. 1:01remain safe? Do glasses need to be worn?
25. 1:05Completely up to you. You check yes.
26. 1:08Don't take them off.
27. 1:10>> Name, date, signature. Job's done.
28. 1:18>> And then on
29. 1:22>> I get my danger tags.
30. 1:27Five.
31. 1:29>> Come down at the appliance.
32. 1:35>> Gloves.
33. 1:44>> I need
34. 1:47put down there.
35. 2:02Don't drop them.
36. 2:06>> I don't like it.
37. 2:20We will teach you how to do this with
38. 2:24two padlocks.
39. 2:26>> According to the assessment rules, you
40. 2:28only need one. All right. BSV stipulated
41. 2:32they wanted a lockable isolator,
42. 2:35>> so why not lock it?
43. 2:37>> All right. Do your assessment elsewhere.
44. 2:40They won't have a padlock for the second
45. 2:43for the
46. 2:50>> pen screw and stick. I think that should
47. 2:52be it.
48. 3:01>> This is the voltmeter you'll use during
49. 3:03the assessment.
50. 3:06>> Right. So,
51. 3:10visual and audio.
52. 3:14>> So you can hear it buzzing.
53. 3:16>> I can't
54. 3:18>> but it is you can hear it in the
55. 3:21assessment room.
56. 3:23Probe also comes off the
57. 3:28banana leads uh for the known source or
58. 3:33the banana outlets and you plug into
59. 3:35that and it'll reach the appliance. No
60. 3:37drama. All right.
61. 3:39>> And
62. 3:41when you're testing at the appliance
63. 3:42terminals,
64. 3:44both probes,
65. 3:48>> it'll read as 240 volts.
66. 3:53>> So, first thing to do is to make sure
67. 3:56that
68. 3:57the earth on the known supply is
69. 4:00actually connected to the earthing
70. 4:01system. We tell you it's a known supply
71. 4:03or it's marked as a known supply, but
72. 4:06how do you know?
73. 4:11Can you get your gloves
74. 4:21bit of a test
75. 4:28roll,
76. 4:30>> hang on to them, make sure there's no
77. 4:32air leaking. A lot of people stick them
78. 4:34up to their ears and what
79. 4:38as long as there's no air leaking,
80. 4:40they're fine.
81. 4:47>> They seem to hold air better if you roll
82. 4:49them on the side.
83. 5:00>> Make sure you look at your leather
84. 5:02gloves.
85. 5:03Make sure there's no visible rips,
86. 5:05tears.
87. 5:11>> Check in between the webbing. Make sure
88. 5:14there's no orange showing from your
89. 5:16internal blobs.
90. 5:30>> Okay. So the gloves are right.
91. 5:33Ask the assessor, is this a switchboard
92. 5:36associated with the appliance?
93. 5:38>> Yes, it is. Is there any essential
94. 5:41services I need to be aware of or any
95. 5:44circuits I can't turn off?
96. 5:47>> No. Okay, fine. Danger tag. It's at the
97. 5:51front of the residence.
98. 5:55>> All my danger tags have three things on
99. 5:58it. name, date, contact number. You want
100. 6:02to put any more on it, that's fine. As
101. 6:04long as you got those three.
102. 6:07>> Next thing to do is to ensure that this
103. 6:10is connected
104. 6:12trailing.
105. 6:32have a work.
106. 6:42Battery's fine. 3 ohm scale
107. 6:50I lead.
108. 7:02I'm reading zero ohms. So I know that's
109. 7:05connected to the earthing system.
110. 7:09Make sure
111. 7:11working fine. It is
112. 7:16turn it off
113. 7:18and I've finished with the trailing
114. 7:21lead. side. Put that away.
115. 7:34>> Next, you want to make sure that
116. 7:36>> the appliance frame is not live.
117. 7:44>> My voltmeter.
118. 7:52All right, now we're good. And
119. 7:55>> make sure my meter's working,
120. 7:58>> which it is
121. 8:01to the frame.
122. 8:16Recheck your meter because you got zero
123. 8:18volts.
124. 8:23>> I'm reading 24 volts.
125. 8:27I know my meter's working.
126. 8:32>> Just going to make sure that the earth
127. 8:34is actually connected to the appliance
128. 8:36frame.
129. 8:46Battery's okay. 3 ohm scale 30 more on
130. 8:50leads.
131. 9:00>> No frame.
132. 9:12There.
133. 9:18It's below five. Not real good. It's
134. 9:21below five.
135. 9:34danger tag on the appliance.
136. 9:38Been called here because something's
137. 9:40wrong with the appliance. We don't know
138. 9:41what
139. 9:43just working. So now I'm going to check
140. 9:46make sure that it's got some high
141. 9:47voltage.
142. 10:03Check my meter
143. 10:1224 vol
144. 10:17active. I've got 24 volts. So, I've got
145. 10:20supply voltage. If you wanted to, you
146. 10:23can go to all the others. Make sure that
147. 10:25you got voltage there.
148. 10:27>> I'm not going to bother.
149. 10:30All you have to do is make sure you got
150. 10:31supply voltage. Don't need to recheck
151. 10:34your meter cuz you know it's working.
152. 10:57cover the appliance.
153. 11:03Tell the assessor that you're about to
154. 11:06start disconnecting. There may be
155. 11:08disruption to power supply. Um, will you
156. 11:12be okay to do so?
157. 11:22There'll be four
158. 11:24>> circuits for each point in the
159. 11:26assessment room.
160. 11:41>> Okay. Not on the workbench.
161. 11:45in your bag, your pocket,
162. 11:48>> bungee cord,
163. 11:50>> lanyard, anywhere. All right, except
164. 11:53flying around.
165. 12:23meter
166. 12:26>> 24 voling
167. 12:35two
168. 12:39>> zero
169. 12:41neutral
170. 12:43zero volts.
171. 12:45Earth
172. 12:480 volts.
173. 12:50The earth's considered a a live terminal
174. 12:53can carry voltage.
175. 12:57And now we go from the earth
176. 13:00to the neutral
177. 13:03>> to active two
178. 13:08>> to active one.
179. 13:11>> Active one to active
180. 13:14two
181. 13:16active one to neutral
182. 13:20>> and neutral to active two.
183. 13:23That's all combinations.
184. 13:27meter.
185. 13:30>> My meter's working.
186. 13:33>> I'm confident that
187. 13:35>> I've disconnected the right circuit and
188. 13:37I've got no voltage there.
189. 13:40Turn off the isolator.
190. 14:06Lock it off.
191. 14:12>> My gloves.
192. 14:21piece of paper. Write down the appliance
193. 14:23details.
194. 14:40Boring diagram.
195. 14:57and
196. 14:59>> switchboard details.
197. 15:10So, I've got dual hot water, 3600 watt,
198. 15:13240 volts. Uh, from the front I got
199. 15:17black, white, then red, and switchboard
200. 15:21number one, row two, number four. It's
201. 15:25all you need.
202. 15:30>> So, I'll begin to disconnect.
203. 15:44It's very
204. 16:11good
205. 16:42Yeah, I have to do the lock nut up as
206. 16:46hard as you as you can or anything like
207. 16:48that. It's just got to be so
208. 16:50there's no single insulated
209. 16:54>> cables coming out. And why is that the
210. 16:56same
211. 16:57spade loss
212. 17:11in
213. 17:26There's a string
214. 17:45Secure a danger tag to the junction box.
215. 17:52The junction box out of harm's way.
216. 18:31Thank you. Stop up.
217. 18:34appliance
218. 18:44is going away to be repaired or
219. 18:46replaced. So
220. 18:49tag off.
221. 18:52>> All right.
222. 18:54>> So tell the assessor that the appliance
223. 18:56been disconnected and um you can not
224. 19:00back by the end of the day. fill out a
225. 19:03uh coe non prescribed
226. 19:07my details his details
227. 19:10>> the details of the work that we've done
228. 19:13today dated sign job's done
229. 19:18questions
230. 19:25>> so he will say all right um
231. 19:29the pl's just been
232. 19:32with the uh new hottie enclosed filled
233. 19:36up with water um right to reconnect.
234. 19:41>> Okay. So asking if anybody's been at the
235. 19:44switchboard that he knows of
236. 19:47um and you'll just check your danger
237. 19:51tags, make sure your your lock still in
238. 19:54place,
239. 19:55>> no one's been at the isolator.
240. 20:00So first thing to do is to ensure that
241. 20:03the appliance is okay to reinstate to
242. 20:08supply.
243. 20:10So
244. 20:11you're going to check
245. 20:14insulation resistance
246. 20:17and earth continuity of the appliance.
247. 20:56Battery Check battery is fine.
248. 20:593 ohm scale
249. 21:02meter
250. 21:05is good from the earth lug.
251. 21:08Going to go to a few spots on the
252. 21:11appliance frame.
253. 21:14Zero ohms.
254. 21:18>> Zero ohms. I'm happy that the frame's
255. 21:21connected to the earth.
256. 21:261,00
257. 21:28500 vol
258. 21:33the earth like I'm going to go to the
259. 21:36active
260. 21:37greater than 200 megga ohm active two
261. 21:41greater than 200 megga ohm neutral
262. 21:45greater than 200 megga ohm check my
263. 21:48meter
264. 21:50meter's working fine so I'm happy that
265. 21:54The earth continuity is is fine and also
266. 21:58insulation resistance minimum
267. 22:00requirement for this appliance is 001
268. 22:04megga ohm. I'm well above that. So um I
269. 22:08can continue with the reconnection of
270. 22:10the appliance.
271. 22:15Next to do is to ensure that
272. 22:20>> the
273. 22:22cables in the junction box haven't been
274. 22:25tampered with in any way.
275. 22:29They haven't become live.
276. 22:32Check your gloves.
277. 22:59You may not
278. 23:10When you're checking your gloves, don't
279. 23:12check them and then put them back on the
280. 23:14ground.
281. 23:16>> Soon as you check them, put them on.
282. 23:43I'm going to get my note out while I'm
283. 23:45here. I'm going to check the appliance
284. 23:47details. Make sure it's light for light,
285. 23:49which it is.
286. 23:51>> Put it down there so I can see the
287. 23:53wiring diagram.
288. 24:0824 vol working from the known earth
289. 24:14to active one.
290. 24:17Nothing
291. 24:19active two.
292. 24:23Nothing.
293. 24:24Neutral.
294. 24:26Nothing
295. 24:28earth
296. 24:31>> zero volts. So from the earth
297. 24:38we go to active two.
298. 24:42Nothing neutral.
299. 24:47Nothing. Active one.
300. 24:50Nothing. Active one to neutral.
301. 24:54Nothing. Active one to active two.
302. 24:59vol and active two to neutral
303. 25:06>> zero vol
304. 25:1224 voltage
305. 25:17at the appliance uh cables
306. 25:23>> so I can rehook them Sorry.
307. 26:06What?
308. 26:30Again,
309. 26:56you don't have to do it up like there's
310. 26:59no tomorrow.
311. 27:07Look up your earth
312. 27:10and you're active as your wiring
313. 27:12diagram.
314. 27:44Next thing to do is make sure that your
315. 27:46earth's actually connected.
316. 27:52Check your battery.
317. 27:56in meter
318. 27:583 ohm scale
319. 28:05earth
320. 28:07points on the frame
321. 28:09about 22
322. 28:16check
323. 28:19zero I know the earth's connected
324. 28:23need that anymore Oh,
325. 28:42top of the appliance terminals.
326. 28:58So to the assessor, you're about to
327. 29:01reconnect supply. They make you
328. 29:02disruption. I'm asking if it's okay for
329. 29:05you to do so.
330. 29:12Remove
331. 29:20your danger tags, your blocks.
332. 29:37So
333. 29:40>> last thing to do
334. 29:42>> is to ensure that you have supply
335. 29:46voltage at the appliance terminals.
336. 29:50So if you've got your gloves off or a
337. 29:52glove,
338. 29:54you need to recheck it.
339. 30:27That's crazy. Check
340. 30:38your motor.
341. 30:44>> M's working. So known Earth
342. 30:52>> to the active got 24 volts. So that's
343. 30:55okay. So, what I'm going to do now is
344. 30:57just go from the known from the active,
345. 31:00sorry, to the neutral.
346. 31:04>> I got the same voltage
347. 31:07um returning from my neutral. So, I know
348. 31:09the neutral is okay.
349. 31:13Don't need that anymore. Don't need to
350. 31:15do any more tests.
351. 31:41The appliance has done.
352. 31:55Right. So, your
353. 31:58>> appliance been tested and reconnected.
354. 32:03>> Um,
355. 32:05I'll be filling out a
356. 32:08certificate of electrical safety for the
357. 32:11works that I've done today.
358. 32:15That be nonprescribed.
359. 32:17I'll have my name, your details,
360. 32:21details of all the work that I've done
361. 32:23today, signed and dated, and you'll
362. 32:27receive that within four business days.
363. 32:32Any questions?
